wheezing question.

my son has been coughing and wheezing for about 4-5 days now. he went to the doctor on Tuesday and they put him on antibiotics for 3 days. he finished them yesterday. he was also running a fever which is why he went to the doctor. Well he was still running a fever at like 2:30 this morning, but I gave him ibuprofen then and he hasn't had . fever since. my question is should I take him in again if he's still wheezing when he breathes. he isn't coughing as much as he had been either. it just sounds horrible when he breathes.

I called up there to talk to a nurse and I had to leave a message. I don't know if it wheezing or crackling or rattling. The doctor did say he was a little concerned about the rattling in his chest when he went in...
